Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to an abdominal wheel. Background Art

[0002] Chinese patent document with publication number CN220608991U discloses an elbow-support abdominal wheel, which includes a connecting frame, wheels and a support rod. There are two wheels, which are respectively arranged on the front and back sides of the connecting frame; a connecting rod penetrates through the connecting frame, and elbow-support areas are arranged on both the left and right sides of the connecting frame. It is characterized in that: at least two connecting rods are provided, and both ends of the at least two connecting rods extend below the elbow-support areas and form supports for the elbow-support areas.

[0003] When using the elbow-support abdominal wheel for abdominal exercise, the elbows of the human body need to support on the elbow-support areas for the forward and backward bending abdominal exercise. During the sliding process of the abdominal wheel, the arms of the human body will also rotate at a certain angle along with the forward or backward sliding of the abdominal wheel. In the above solution, when using the abdominal wheel for exercise, the elbow-support areas are fixed and cannot adapt to the rotation of the human arms. And users often adjust their arms or exercise postures to adapt to the movement of the abdominal wheel because the elbow-support areas cannot adapt to the rotation of the arms. Therefore, discomfort is often felt during use, and this will also reduce the exercise effect of the abdominal wheel. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an abdominal wheel with a reasonable structure and more in line with ergonomics.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] An abdominal wheel includes an elbow-support component and a sliding mechanism. The sliding mechanism is provided with walking wheels so that the sliding mechanism can slide back and forth. The elbow-support component is arranged on the sliding mechanism. It is characterized in that: the elbow-support component is arranged on the sliding mechanism so as to be able to rotate forward and backward by a certain angle through a horizontally arranged pivot shaft.

[0007] By adopting the above solution, the elbow-support component is arranged on the sliding mechanism so as to be able to rotate forward and backward through a horizontally arranged pivot shaft. In this way, when in use, the elbows can be supported on the elbow-support component, and abdominal exercise of sliding back and forth can be carried out by using the sliding mechanism. And when the sliding mechanism slides forward, the elbow-support component can rotate backward by a certain angle around the axis of the pivot shaft. When the sliding mechanism slides backward, the elbow-support component can rotate forward by a certain angle around the axis of the pivot shaft. In this way, it can be more in line with the ergonomics during exercise and make users more comfortable when using.

[0008] The elbow-support component can rotate forward relative to the horizontal plane by 0-5 degrees, and the elbow-support component can rotate backward relative to the horizontal plane by 10-20 degrees.

[0009] By adopting the above solution, when the sliding mechanism slides forward or backward, the elbow support component can be rotated forward 0-5 degrees or backward 10-20 degrees relative to the horizontal plane, which is more ergonomic and makes the user more comfortable when using it.

[0010] The sliding mechanism includes a wheel frame and a running wheel. The pivot shaft is fixedly arranged at the bottom of the elbow support component. The wheel frame is rotatably arranged on the pivot shaft. A pivot hole for the pivot shaft to pass through is arranged on the wheel frame. The running wheel is rotatably arranged on the wheel frame.

[0011] By adopting the above solution, the installation of the sliding mechanism can be facilitated. During installation, it is only necessary to install the walking wheel on the wheel frame, then pass the pivot shaft through the pivot hole, and fix the pivot shaft to the bottom of the toggle support component.

[0012] A front limiting portion and a rear limiting portion are arranged at the bottom of the elbow support component, and the front limiting portion and the rear limiting portion can be abutted against the wheel frame to limit the rotation angle of the elbow support component.

[0013] By adopting the above scheme, a front limit portion and a rear limit portion are provided at the bottom of the elbow support component, which can abut against the wheel frame to limit the rotation angle of the elbow support component, prevent the elbow support component from rotating too much, and make the rotation angle of the elbow support component within a reasonable range.

[0014] The sliding mechanism includes two wheel frames, which are arranged transversely. A first meshing portion is provided on the side of one wheel frame, and a second meshing portion that can mesh with the first meshing portion is provided on the side of the other wheel frame. The first meshing portion cooperates with the second meshing portion to prevent the two wheel frames from rotating relative to each other.

[0015] By adopting the above scheme, the two wheel frames can engage with each other through the first engaging portion and the second engaging portion so that the two wheel frames will not rotate relative to each other. This can make the sliding mechanism more stable when sliding, and can also prevent the user from causing uncoordinated rotation of the two wheel frames due to improper operation, thereby preventing the movement effect from being weakened.

[0016] The wheel frame is provided with two traveling wheels which are spaced apart from each other in front and behind.

[0017] By adopting the above solution, in the case of a two-wheel frame, there are four running wheels arranged at intervals in front and behind, which makes the sliding mechanism more stable when in use.

[0018] The wheel frame comprises two side plates and a separator, the two side plates are triangular and arranged in parallel and spaced apart, the separator is connected between the two side plates, and the running wheel is rotatably arranged between the two side plates through a wheel axle.

[0019] By adopting the above solution, the two side plates of the triangle have better stability. The walking wheels are rotatably arranged between the two side plates through the wheel axles, which facilitates the assembly and fixation of the walking wheels and also makes the walking wheels more stable after assembly.

[0020] The sliding mechanism includes at least one front walking wheel and at least one rear walking wheel arranged at intervals front and back.

[0021] By adopting the above solution, by using the front walking wheel and the rear walking wheel arranged at intervals front and back, the sliding mechanism can be more stable during use.

[0022] The elbow support member includes a plate-shaped main body and an armrest. An elbow support portion with a left-right interval is arranged at the top of the plate-shaped main body. The armrest is arranged at the front end of the plate-shaped main body, and a buffer pad is arranged on the elbow support portion.

[0023] By adopting the above solution, when in use, the elbows can be supported on the elbow support portion, and the armrest located at the front end of the plate-shaped main body can be held to perform abdominal exercises before and after bending forward. Arranging a buffer pad on the elbow support portion can increase the comfort of the user during use.

[0024] An installation groove adapted to both ends of the pivot shaft is formed at the bottom of the elbow support member.

[0025] By adopting the above solution, both ends of the pivot shaft can be installed in the installation groove through fasteners, which facilitates the installation of the pivot shaft and also prevents it from displacing during movement. Description of the Drawings
